Appl. No.:

7/863612

Inventors:

Dennis C. Robinson - Marlboro MA
Jeffrey P. Copeland - Holden MA

Assignee:

Digital Equipment Corporation - Maynard MA

International Classification:

H04N 530
H05K 500
H05K 900
H01J 152

US Classification:

348825

Abstract:

An computer assembly having an integral video display and processor subsystem in a single enclosure is described. The assembly contains an electrically conductive safety wall inside the enclosure which separates the interior of the enclosure into a high-voltage region where the video display components are mounted, and a low-voltage region where the processor subsystem is mounted. The enclosure has a removable rear cover which allows access to the processor subsystem for upgrading memory. An electrically conductive liner is attached to the rear cover for EMI shielding of the low-voltage region.

International Classification:

H05K 900

US Classification:

174 35R

Abstract:

The disclosed invention relates to a video display system having a device for shielding electromagnetic radiation emitted from electrical wires which connect a video amplifier to a cathode ray tube. The device uses inexpensive unshielded wires which are recessed within a conductive shielding enclosure. The wires are connected to the cathode ray tube by a socket which is positioned at an access opening in the shielding enclosure. The invention further relates to a device for mounting a shielding enclosure to a base using tabs on the enclosure which are captured in an interference fit between the surface of the base and brackets coupled to the base.
